I Be it'known that 1, Eu JONES, L citizen elevation taken through a well strainer conf the United States, residing at Lexington, stru'ctcd in accordam-e with an embodiment in the county of Henderson, and State of of my invention;

In order that my invention may be the The cups C are each ofthe same c0nstrucbetter understood, I will not proceed to detion and comprise an outer wall 10 prefer- 1110 60 scribe the same with reference to the accomably slotted or otherwise reticulated, the panying drawings, where1n: slots or openings 11 being of such size. as

- to efl'ectively maintain Within a cup a filler of relatively coarse sand. Through the instrumentality of the cups C the slitted portion of the strainer S is surrounded or packed with an outer layer of this course sand which permits a ready entry of the water within the strainer but excludes from entry within the strainer t-he finer sand or sand grains of a. size which would other wise pass through the slits of the strainer.

The lower or smaller endof each of the cups C is of a diameter to snugly receive the strainer S and extending inwardly from the wall 10 are the ribs 12 the lower portions a of which being on an angle to have direct contact with the periphery of the strainer while the upper edge ortions b are adapted for contact with the ower portion of the cup C extending therein. The lowermost cup 0 has contact with the outstanding flange 2 of the plug 1 hereinbefore referred to while the reduced portion of the pipe section 5, when applied, engages the edges 6 of the flanges 12 of the uppermost cup C whereby all of the on s C are effectively maintained in desire plied osition.

To urther strengthen or reinforce a cup C the wall 10 thereof is provided therearound with the corrugations 14.

The upper or larger end of each of the cups C is also disposed slightly inwardly, as at 15, to obviate hanging on the ends of the well pipe section novel couplings should it be desired to raise the strainer 1n the casing.

The'cups G are installed on the strainer S by slipping them on from the upper end it being understood that the required numher of cups C are to be employed until the slitted portion of the strainer is entirely surrounded with said cups.

By having the walls 10 of the cups C perforated the coarse sand is effectively held against the strainer S and at the same time the capacity of said strainer is materially increased. By stren thening or reinforcing each of the cups 6 through the medium of the flanges 12 and also by the corruga: tions 14 the same will effectively resist strain or pressure imposed thereupon incident to its use and also to such strain or pressure which may be imposed thereon during shipment or in storage particularly when unapplied to a strainer.

From the fore oing description it is thought to be ObVlOllS that a well strainer constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susce tible of some change and modification witiiout departing from the principles'and spiritthereof and for this reason I do not wish to be understood as limit- 7 ing myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim 1. In combination with a tubular slitted well strainer, cups mounted on the strainer and surrounding the slitted portion thereof, an upper cup extendin within the adjacent lower cup, said cups being adapted to hold a filtering medium, the wall of each of the cups being perforated.

2. In combination with a tubular slitted well strainer, cups mounted on the strainer and surrounding the slitted rtion thereof, an upper cup extending within the adjacent lower cup, said cups bein adapted to hold a filtering medium, sai cups being frustro-conical with the smaller ends 'disposed downwardly.

3. In combination with a tubular slitted well strainer, cups mounted on the strainer and surrounding the slitted ortion thereof, an upper cup extending within the adjacent lower cup, said cups being ada ted to hold a filtering medium, each of said cups being provided with inwardly disposed flanges for contact with the strainer.

4. In combination with a tubular slitted well strainer, cups mounted on the strainer and surrounding the slitted portion thereof,

an upper cup extending within the adjacent ower cup, said cups bein adapted to hold a filtering medium, and means for holding the cups in applied position.

5. In combination with a tubular slitted well strainer, cups mounted on the strainer and surrounding the slitted portion thereof, an upper cup extending within the adjacent lower cup, said cups being adapted to hold a filtering medium, and means coacting with the end cups for holding all of the cups in applied position.

6. In combination with a. tubular slitted well strainer, cups mounted on the strainer and surrounding the slitted portion thereof, an upper cup extending within the adjacent lower cup, said cups being adapted to hold a filtering medium, the wall of each of the cups being corrugated.

7. In combination with a tubular slitted well strainer, cups mounted on the strainer and surrounding the slitted portion thereof, an upper cup extending within the adjacent lower cup, said cups being adapted to hold a filtering medium, each of the cups being provided with inwardly disposed flanges for contact with the strainer and for contact with the portion of the cup extending therein.

8. In combination with a well strainer, a pipe section secured to the upper extremity thereof, the upper portion of the pi tion being enlarged, and a packing errule carried by the enlarged portion of the pipe section, and a disc carried by the pipe secsection. tion inwardly of the packing and provided 9.
